Additional Details

Specific electrical characteristics such as inductance, impedance at various frequencies, rated current, and DC resistance are critical for selecting the right choke for a specific application. Consult the manufacturer's datasheet for precise specifications. The PA2467NL is designed for reflow soldering processes. The choke uses ferrite core material and is wound to provide high common mode impedance while maintaining low differential mode impedance. It operates within a specified temperature range, often from -40°C to +85°C or wider, and is typically tested for hipot strength to ensure isolation and safety. The NL suffix indicates lead-free terminations.
